Abstract: 1345216 Fuel injection systems BENDIX CORP 11 Oct 1971 [15 Oct 1970] 47218/71 Heading G1N In an I.C. engine intermittent fuel injection system having at least two fuel injection groups, electrical pulses are applied to the injectors of each group in such a manner that the open times of the injectors of one group can overlap with those of the injectors of another group. As shown, engine rotation initiated pulses TR1, TR2 are applied to a pulse generator 10, TR1 being applied to AND gate 51 and TR2 to AND gate 52. A signal generator 10<SP>7</SP> provides a pulse train Á 2 , having pulse durations T1 controlled by a sensed engine parameter, e.g. absolute intake manifold pressure, which is applied to both gates 51, 52 so that gate 51 provides a pulse train Á 2 ' and gate 52 provides a pulse train Á 2 ". These pulse trains are applied to a bi-stable multi-vibrator 59 which provides output pulse trains Á 6 , Á 6 ' respectively to AND gates 53, 54 in a second pulse generator 30, to a second signal generator 30' which provides a pulse train Á 3  to both gates 53, 54, the duration T2 of these pulses being controlled by a sensed engine parameter, e.g. differential intake manifold pressure, and to OR gates 55, 56 respectively. The output pulses Á 3 ', Á 3 " of AND gates 53, 54 are respectively applied to the OR gates 55, 56 whereby gate 55 provides an output pulse train Á 5  of pulse duration T1 + T2 to one injection group 80, and gate 56 provides output pulse train Á 7  of pulse duration T1 + T2 to the other injection group 90. The pulses of train Á 5  are initiated with the pulses TR1 and the pulses of train Á 7  are initiated with the pulses TR2, the durations T1 + T2, however, being capable of being larger than the durations of TR1 and TR1 to provide the desired overlap.

[Also in Division B5] Crimped filaments are made by passing filaments of an extrudable organic thermoplastic material through a heating zone in which each filament is eccentrically or non-uniformly heated so that it is rendered elastic and latent stress factors are imparted to it, subsequently stretching the filaments at a lower temperature to orient them, and to allow the latent stress factors to develop, and then relaxing the filaments at a temperature higher than the second order transition temperature but below the softening point. The heating zone may be a heated surface e.g.a bar or rod, and the filaments, e.g. isotactic polypropylene filaments, may be heated thereon above their melting point. The subsequent stretching e.g. 1. 5 to 5 times, may be carried out on heated rolls. In one embodiment, Fig. 1,filaments F, from meltspinning jet 15 pass over guide bars 17 and 21, between which is an electrically heated metal rod 19, which the filaments contact in spaced-apart relationship. The filaments then pass over feed rolls 25 and guide 27 to heated stretch rolls 29, 30 and thence via guides 31, 33 and 35 to a heating chamber 37. During its passage therethrough, the filament yarn is relaxed under very low tension to develop crimp. The crimped yarn then passes over feed rolls 39 guide 41 and tension control device 43 to take up device 45. If desired, the crimp may be partially developed in chamber 37 and crimp development completed by subsequent heating of the yarn or of the fabric into which the yarn is made. The yarn emerging from the heating zone may be wound on to a bobbin with low twist before being unwound from the bobbin and stretched.

The gel may be made by washing Ti(OH) 4  until the wash water has pH # 7 and specific conductivity of # 10<SP>4</SP> Ámhos, adding acid to bring pH to < 2À8, but preferably > 1À0, holding the slurry until sol. formation occurs and then removing water therefrom to form the gel. Alternately, an aqueous solution of a Ti salt, e.g. TiCl 4  may be contacted with a substance which removes anions so as to reduce the anion/Ti (IV) ratio to < 1 and then removing water from the resultant sol. The anion exchanger may be solid or liquid, e.g. a solution of a long chain aliphatic amine in 1,1,1-trichloroethane. The sols may be converted to the gel by evaporation, spray drying or dehydration in a lyophelic solvent, e.g. 2-ethylhexanol. The gel when redispersed forms a stable sol. which may be re-gelled into spherical particls of 4-2500 Á in size by dehydration in lyophilic solvent or chemical gelation. The gel particles may be calcined at 800-1000‹ C. to form TiO 2  spheres. Cubic TiC may be made by mixing the redispersed gel with finely divided C and a wetting agent, e.g. polyvinyl alcohol, dehydrating the mixture and calcining, e.g. at 900-1500‹ C. in a fluidized bed.
